JEGS Performance Products 80524 Details

Note: This method is not recommended for use on engines where the piston stop can contact the valves (i.e. Chevy angle plug heads). Each engine is different, and the design of the piston / chamber / spark plug / valve locations may cause interference between the piston stop & valves. If this is the case, you should use another method to find Top Dead Center.

Provides a positive stop to locate the piston at top dead center for cam indexing, valve adjustment, and distributor installation. Threads into any cylinder head with a 14mm spark plug hole. Zinc dichromate finish for durability and corrosion resistance. Made in the USA.

Rounded end/Tip----------NOT Flat end/TipApr2015-The picture doesnt show it but when I received this tool the tip was rounded instead of the flat end/tip design. Since this a "base model" part, Im not sure how long the part# will remain to having the rounded tip. March2014-I bought a "base model" TDC tool that looks just like the 1 pictured but from S U M M I T & it had the flat end/tip design.
I LIKE THE ROUNDED END/TIP DESIGN BETTER.

Needed to confirm TDC on my SBC 350. Super easy to use, and lined me up perfectly at 0*. Couple bucks for peace of mind knowing my timing was spot on.
